When people say that "Training to failure will not caus overtraining, BUT it is very taxing on the CNS," what do they mean?
Central Nervous System? What does that have to do with anything?

The CNS is your central nervous system. It is involved in all nerve response and muscle activity. You can train your CNS for several types of funtionality, such as endurance, power, strength, etc.
Now about the CNS overload part. By doing too much working out, especially heavy compound exercises to failure too much too often, your CNS will not be able to keep up with the work and the impulses it sends will become weaker, and your CNS will fatigue. You will generally feel weaker, feel bad, and need time off to let your CNS recuperate.
And training to failure is a very good cause to overtraining, as is working out with over 90% max on a single exercise for some weeks straight to failure.
The CNS is VERY important!!

As i posted in a thread awhile back:
Well you could look in any biology textbook and it would tell you the CNs is responsible for coordinating movements, weight training has a heavy effect but lets go to actual info.
As stated in the book Supertraining by Mel Siff
"Overtraining and exhaustion are both consequences of imbalance between stress and the adaptability of the body. Successful adaption implicates supercompensatory (adaptive reconstruction) processes that lead to a higher functional level of the body, wheras unsuccessful adaption depletes the current adaption reserves.
...
Energy exchanges in the body are involved with many other events such as tissue repair and nervous impulses. It follows that overtraining is closely related to an inadequet rate of recovery and adaption of:
-The energy systems of the body
-cell repair and growth mechanisms
-hormonal systems
-nervous processes
...
There are two types of overtraining: general and local. General overtraining affects the whole body and results in stagnation of a decrease in a preformance, wheras local overtraining affects a specific bodypart.
...
Adaption to physical, pyschological, or enviromental stress depends on the inextricable links (*my quick explaination* fast and slow control which is divided from the muscular systems, the CNS splits to fast and the endocrine system splits to slow, they meet at Hypothalamus**) between the central nervous system (the fast control system of the body) and the endocrine system of the body (the slow control system).Any changes in the Central Nervous System and endocrine systems can affect performance in the muscular system.
... (a) A-overtraining (Addisonic overtraining) named after Addison's disease, which is associated with diminished activity of the adrenal glands. This category of overtraining affects predominantly the parasympathetic pathways of the autnomic nervous system and is difficult to detect early, due to the absense of any dramatic symptoms. Suspicion that something is amiss may be aroused by the appearance of stagnation or deterioration in the athlete's performance.
(b) B-overtraining (Basedowic overtraining), named after Basedow's disease , which is associated with thyroid hyperactivity. This category of overtraining effects predominantly the sympathetic pathways of the autonomic nervous system and, as the classical type of overtraining with its abundance of symptoms, is easy to diagnose
...In the case of strength training, overtraining injuries may be the result of too many repetions or sets, regular training with near maximum loads, training the same muscle groups too frequently, inadequet recovery periods, insufficent rest or faulty execution of any movement."
That information was gathered from pages 437-439 in the book Supertraining. The book itself has over 13 pages of bibliography and references. I hope some of that information was able to prove to you about the link between overtraining and the CNS as well as explain it somewhat."Power is the ultimate aphrodisiac." -Henry Kissinger
"Beware that, when fighting monsters, you yourself do not become a monster . . . for when you gaze long into the abyss, the abyss gazes also into you." -Friedrich Nietzsche
